Hi guys. Just wondering if anyone is running the Wolf 3D and using stock injectors? I'd like to keep running 8-10 psi, which was possible before using my RRFPR to ramp up fuel pressure. Is it possible to use the RRFPR in tandem with the Wolf, or should I just wait until I get the injectors? Thanks.

I have to disagree - it is very unlikely 370cc injectors can support 15 psi of boost on a EJ25 without bumping up the fuel pressure. Shiv ran out of fuel with his 550cc injectors at 14-15psi when he was pushing his engine to the limits. Even with my own car, I run 60-65% duty cycles at 7psi with 550cc injectors, indicating that I'm using ~360cc already.

On pump gas, I ran out of fuel (85+% duty cycle) at 10psi and 280 wheel hp. On a race gas/pump gas mix (which allowed a leaner fuel curve), I ran out of fuel at 13psi at 296 wheel hp. Injectors actually went wide open in the end and ran me a little too rich up top. I suppose I could have raised the boost even more to compensate but that would have been risky, to say the least

just so you know... I was stuck at 5,500 rpm with that setting, the crank sensor shook above that and wouldn't allow the revs to be read....
so there it is, I agree, I dont think 370cc's will hold up at full rpm at that boost either, but I never went lean and didn't ping either...
